Electromagnetic pulse welding (EMPW) is an environmentally friendly and advanced manufacturing technology. Researches find the macro-morphology of EMPW joint sheets presents a multilayer ellipse. The experiments Al-Cu Al-Mg were carried out, both micro-morphology showed there collision zone, bonding zone affecting in joint, presenting elliptical morphology, which was independent material. welded seam zone. 3D multiphysics simulation results also that distribution plastic deformation Al...
Electromagnetic forming (EMF) has been widely applied in industries. However, it's still hard to form thick or metal work pieces due the limitation of its system power. Moreover, increasing input voltage capacitors may cause problem insulation, reduce lifetime performance devices, and lead cost increase safety issue. Therefore, this paper proposes a novel technology named electromagnetic heating (EMHF), which combines EMF with induction (EIH) based on their similar working principles make it...
Electromagnetic pulse forming (EMPF) is a type of electromagnetic manufacturing technology which produces powerful Lorentz force to change the shape or form work piece. In this paper, 6.75-kJ/15-kV compact EMPF system based on RVU-43 trigger vacuum switch designed, fabricated and tested. The has good performance in high-voltage discharge process that can withstand 25 kV conduct 400 kA. A source for transformer solid-state generate rectangular an adjustable amplitude 0-5 width μs. simulation...
Limited by the current capacity of discharge switch, amplitude circuit pulse electromagnetic welding (EMPW) system is at a relatively low level, which greatly limits application range EMPW technology. In this paper, trigger vacuum switch (TVS) was selected as and double-switch synchronous conduction scheme proposed. Based on two 20 kV/28 kJ single-switch generation modular, kV/56 designed, could generate with peak value 360 kA when charging voltage 16 kV. Finally, effective 1 mm Mg/Al alloy...
Objective To observe the curative effect of subdural effusion treated and prevented with bandage secondary to decompressive craniectomy performed in patients traumatic brain injury. Method 55 cases injury were undergone from September 2009 April 2015 department neurosurgery second people’s hospital Jingzhou, those randomly divided into bone window compression group(n=26) normal group (n=29). Analysis difference incidence effusion, occurrence time postoperative GOS score between two...
The current research about Power-MEMS is mentioned. A micro turbine-generator system which aims to generate ultra-high power density at a high speed 105r/min put forward. Its work-principle adequately introduced. performance-tests of the are accomplished on test-bench has been specially designed. It can be seen that able 0.6W output-power and maximal voltage 12.5V. Moreover, tested in four conditions order investigate how pressure, volume flow temperature inlet gas affect system’s performance.
In recent years, magnetic pulse welding (MPW) technology has shown broad application prospects because of its unique advantages in dissimilar metal welding. The jet can clean up the dirt and oxide layer on surface workpiece promote metallurgical bonding, which is key step MPW process. To explore formation mechanism characteristics jet, an experiment platform integrated observation system for was established this work to carry out experiments Al Cu sheets. complete trajectory captured, a...
